Description
A. FAR: 153? ND FEEDER DISINTEGRATOR A AUGUST BARKER, F KUSHAGHT, NEAR ZURICH, SWITZERLAND, ASSIGNOR TO THE FIRM G. HUNZIKER, OF RUTI, CANTO'N ZURICH, SWITZERLAND.
DISINTEG-RATOR AND Application filed April 18, 1928. Serial No. 632,348
To all whom e't may concern:
Be it known that 1, Answer Fannnma citizen of the Republic of Switzerland, residing at 18 Rosenstrasse, Kusnacht, near Zurich, Switzerland, have invented certain new and useful Improvements in Disintegrators and Feeders, of which the follow ing is a specification, reference being had therein to the accompanying drawing.
The invention has reference to a disintegrator which is particularly suited for supplying coal dust to coal (lust burning furnaces and which comprises a rotating hollow body provided at its outer circumference with heaters, whereby the produced dust (coal dust) has to flow through the hollow rotor on leavin" the mill. Up to the present devices of this type were provided with a c 'lindrical hollow body i. c. with a hollow shaft having holes in its shell for the dust to pass through. Such devices are, however, disadvantageous owmg to the cen-' trit'ugal action causing the dust to adhere to the inner wall of the hollow shaft and form lumps which fall off from time to time. The formation of lumps occurs especially when the material to he disintegrated is not perfectly dry, and it causes a very irregular delivery of dust.
This drawback is overcome by the disintegrator according to the present invention in which the rotating hollow body through which the disintegrated material passes consists of a drum the shell of which widens out in the direction in which the disintegrated material or dust leaves the disintegrator. With this constructional form of the hollow body, the centrifugal action inside thehollow body facilitates the discharge of the treated material so that an accumulation of the dust inside the hollow body is prevented.
Constructional examples of the subject matter of the present invention are illustrated on theaccompanying drawings. in which:
Fig. l is a vertical longitudinal section through a first form and Fig. 2 is a plan view thereof,
Fig. 3 shows part of a vertical section along the line IH-lll of Fig. l.
Figs. 4. and show parts of longitudinal vertical sections of modified forms.
In these drawings, 1 denotes the belt driven shaft of the disinte rator and 2 is the casing, the top half 2' 0 which is hinged to the lower half. 3 is a duct through which the material to he disintegrated is supplied. It is assumed that coal is disintegrated in this mill, the coal being subjected to a preliminary disintegration by means of a cutter 4. To the cutter s rotation is imparted by a belt drive 5 from the mill shaft 1, a stationary shell 6 partly surrounds the cutter, the coal, on being filled into the hopper 7, is fed by gravity to the cutter. The shell 6 determines the passage area from the hopper 7 to the feed duct 3 of the mill and this passage area may he manually adjusted or completely shut ed by actuating the worm gear 8 and causing thereby a turning of the shell. -9 denotes the drum secured to the shaft and rotating with the latter, the exterior of the shell or the drum is provided with heaters 10 the working faces of which are at an. angle to the axis of the mill and further holes 11 are provided in the shell to permit the material treated to pass through. The drum widens out in the direction in-whioh the treated material leaves the disintegrator and at the wider end of the drum a fan with blades 12 is arranged. 13' denotes the fan casing connected to the casing 2 oflhe disintegrator, from which casing the dust into which the treated material has been converted is sucked :I'Kl is dclivcrcd. for instance, to the furnace in which the coal dust is burned. Rings 1-1 the inner circumference of which is provided with scrrutions or teeth are arranged in the mill casing between the rows formed by l'hc hcatcrs 10. The force with which the mulcrial is thrown by the rotating heaters in a radial direction against the mill casing and the serrated rings l4 greatl cnhanccs the disintegrating process.
According tp the first constructional form illustrated in Figs. l-3 the drum is provided with a conical shell. The heaters 10 arc fixcd to the drum in an adjustable manncr with regard to the adjacent'row of the holes 11 by means of bolts passing through slots arrangcd in a foot portion of the beatcrs. so that the foot portion nay close to a great r or smaller cxtcnt a hole ll situated behind the heater when looking in the direction of rotation. In this manner a regulation of the suction acting on the dust tit? ' by whim ioozg moons to drive ooigi fan, m-som to alien the speed of the fan reiaiivoly jo the speed of tho rofior. l
5. In a, disintogmmr prtiouiniiy for feeding coal dust fumacos in ooznbina tion, a stationary casing, n Poi/oi" formed as a hollow drum whoso shoii is shopofi on n convex surface of a, oono so inn; "the shell Widens out in the dimotion in which izho treated matoi-ial loaves iho ioinfiegmton, Motors fixed to the outside of said shoifl and acting upon the material to bo (iisin6oa rosioii fan situated at the large end of sai rotor and ads, ted to generate the suction action the disintegrated materiai is re moved, means to drive said rotor, ans :1 drivgem' il ioindi'ng step puiio'ys for driving soiii fan and to alter the good of the ion relatively to tho speed 0:? tho rotor.
In a disintogx'aior for fosfiing cool-damn furnaces the combination with a hoiiow yoior having oponings thez'oiiirough, dissintograting means on the exterior of the rotor imgarrting contrifugai action to tho mammal on moons to'exhznist the oolnminutod moiei-ia'i through the oentro oi said rotor contmiry to 533143 centrifugal action on tho oomminnioii moierial.
8. in o. disintegrate! for fooiiing coal dust furnaces, tionary casing and. a hollow, gaerforated, a rotor and boaters fi -hereon; of a fan to exboost the centre of said hollow 9, in a disintegrator for feeding coal dust to furnaces, the combination with a stationary casing, a shaft therein, and a hollow perforated substantially conical rotor on said shaft; of an exhaust, fan at one and of (said drum, said fan being driven from saiii oimfi and comminuting moans betwoen ihe a'otor and casing.
